Hide category heading attribute if it's empty

[dbabaev]

Hi folks,

Can someone please help me with the following. We display a list of categories the product belongs to in the following code. However, when there are no category headings the "Application Guide" row still appears. I believe we need some sort of an "if" statement but I tried everything and couldn't make it work. Basically, I need the Application Guide row to disappear if there are no Category Headings for the product.

The regular attributes do hide if they are empty.

<?php
    $_helper = $this->helper('catalog/output');
    $_product = $this->getProduct();
	$currentCatIds = $_product->getCategoryIds();
	$catCollection = Mage::getResourceModel('catalog/category_collection')
	->addAttributeToSelect('*')
	->addAttributeToFilter('entity_id', $currentCatIds)
	->addAttributeToFilter('is_active', 1)
	->setOrder('creareseo_heading', 'asc')
	->addIsActiveFilter();
?>
<?php if($_additional = $this->getAdditionalData()): ?>
    <h2><?php echo $this->__('Additional Information') ?></h2>
    <table class="data-table" id="product-attribute-specs-table">
        <col width="25%" />
        <col />
        <tbody>
        <?php foreach ($_additional as $_data): ?>
        <?php $_attribute = $_product->getResource()->getAttribute($_data['code']);
		if (!is_null($_product->getData($_attribute->getAttributeCode())) && ((string)$_attribute->getFrontend()->getValue($_product) != '')) { ?>
            <tr>
                <th class="label"><?php echo $this->escapeHtml($this->__($_data['label'])) ?></th>
                <td class="data"><?php echo $_helper->productAttribute($_product, $_data['value'], $_data['code']) ?></td>
            </tr>
        <?php } ?>
		<?php endforeach; ?>
            <tr>
                <th class="label"><?php echo $this->__('Application Guide') ?></th>
                <td class="data">
                    <ul>
                    <?php foreach($catCollection as $cat): ?>
                        <li><?php echo $cat->getCreareseoHeading() ?></li>
                    <?php endforeach; ?>
                    </ul>
                </td>
            </tr>
        </tbody>
    </table>
    <script type="text/javascript">decorateTable('product-attribute-specs-table')</script>
<?php endif;?>

Thanks in advance!

 if(sizeof($_additional))
{
